This invention relates to improvements in extensio-n curtain rod assembly.

This invention relates to extension curtain rods and particularly to those formed of sheet metal. It has for its objects:

First, to produce a new andfimproved sheet' metal extension rod assembly.

Second, to provide such an assembly in which the extension rod is bowed outwardly from the window frame and the brackets forming a portion of the assembly.

Third, to provide such an extension rod in which the rod is formed of relatively dat telescoping sheet metal sections giving the desired rigidity with a minimum of weight which rod as- Sembly may be installed widths.

Fourth, to provide such a rod assembly which may be made up in standard sections and sold as units to be installed by the ultimate consumer regardless of the width of the window to which it is desired to apply the rod.

` Fifth, to provide such a rod assembly in which the rod is rmly held against sagging and in a horizontal position.

Further objects and advantages pertaining to details and economies of construction and operation will appear from the description to follow. The invention isv dened in the claims. A preL ferred embodiment of my invention is illustrated in the accompanying drawing, in which:

Fig. l is a top plan view of the curtain rod assembly embodying my invention.

Fig. 1-A is an identical view of the same rod assembly installed on a. narrower window.

Fig. 2 is a detail view showing the ment of the rod and the bracket.

Fig. 3 is a detail top plan view of the end of on win'dows of different the curtain'rod and its bracket showing in full lines the position of the rod on a narrow window A and in dotted lines the position of the rod on aV wider window.

Fig. il is a detail sectional view taken on line iL--t oi' Figs. 1 and 3.

Fig. 5 is a detail sectional `view taken on line 5 5 of Fig. 3.

Referring to the drawing, a window casing i is shown to which the bracketsi and the curtain rod t of my rod assembly are fastened. It will be noted that the brackets 2 have bases t whichr may be suitably fastened to a window casing by' means of screws or` the like 5. The free ends ofv the brackets are bent at an angle as shown at and each carries on its end a pair of spaced hooks 'i and d which are vertically alined. These arrangeses. semi No. 209,526

(ci. 15s-22) brackets are preferably made of sheet metal in the form of stampings. The curtain rod 3 which is bowed outwardly from a straight line between the brackets 2 and from the window casing i is formed of a band of relatively iiat telescoping d sheet metal rod sections 9 and l0. These rod sections are formed with a C-shapedcross section as is indicated in Fig. 5 and the section 9 telescopes into the section I0. The rod sections are identically curved atwise as indicated in Fig. 1 i@ into circular arcs so that they may be telescoped from the position shown in Fig. 1 to the position shown in Fig. 1-A. They are both formed as arcs of the same circle which permits this telescoping. id The brackets 2 hold the rod 3 in a horizontal position as indicated in Fig. 2 and prevent the` downward twisting of the rod.- This is accomplishedrby the arrangement of pairs of spaced vertically alined apertures il and I2 disposed in the lower and upper edges of the free ends of the rod sections El and it which form the curtain rod 3. These apertures li and l2 are, as is best shown in Fig. 3, of sucient size to be pivotally mounted on the hooks 'i and t and it will be apparent that the rod is detachably mounted in the brackets by merely fitting the hooks i and t into the apertures H and it. By providing for the support of the rod at both the upper and` lower edges of the ends, it is possible to maintain the rod in horizontal position and prevent twisting and sagging thereof. By providing the pivotal mounting, it is possible to apply the same rod to dierent widths of windows as shown specifically in Figs. 1 and 1-A. It will be noted that in Fig. 1 the angle between the brackets i and the'rod sections 9 and lil is less than the angle between the same rod sections d and ld and the brackets 2 in Fig. l-A. It will be apparent that .as the rod is shortened, the angle between the brackets and the rod sections becomes greater as is shown in the full line position in Fig. 3, the dotted line position in Fig. 3 indicating the positon of the rod when it is extended more than in the full line position. p

By combining these features it is possible to make a telescoping extension rod of sheet metal which may be fitted to several different sizes of windows within the extension limits ofthe rod and it will be apparent that regardless of the Spacing of the'brackets within these limits, the rod will be rmly held in horizontal position with its flat portion vertically disposed, giving the desired rigidity and lightness ofweight'. It will be apparent that the parts for this rod assembly may be made up and sold to the ultimate consumer who may install the rods in any suitable window spacing and that it will not be necessary to cut each rod length to order and to provideV a separate set of brackets foreach individual mounting of the rod.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a curtain rod having a pair of brackets adapted to be attached to a window casing, a pair of relatively nat telescoping sheet metal rod sections identically curved atwise into circular arcs forming a curtain rod bowed horizontally away from a line between said brackets, and means for pivotally and detachably connecting the upper and lower edges of the free ends of said rod sections forming the ends of said curtain rod to said brackets on vertical axes with the rod bowing outwardly from the window casing to which the brackets are attached in use, whereby said rod will be held against twisting and sagging from the horizontal position with its at portions vertically disposed regardless of the spacing of the brackets. within the extension limits of the curtain rod.

2. In a curtain rod having a pair of brackets adapted to be attached to a window casing, a pair of relatively at telescoping sheet metal rod sections identically curved atwise into circular arcs forming a curtain rod bowed horizontally away from a line between said brackets, and

means for pivotally connecting the upper and lower edges of the free ends of said rod sections forming the ends of said curtain rod to said `will be held against twisting and sagging from the horizontal position with its at portions vertically disposed regardless of the spacing of the brackets within the extension limits of the curtain rod.

3. In a curtain rod having a pair of brackets adapted to be attached to a Window casing, a pair of hook members disposed .in vertically alined relationship on each bracket, a pair of relatively hat telescoping sheet metal rod sections identically curved flatwise into circular arcs forming a curtain rod bowed horizontally away from a line between said brackets, and means for pivotally connecting the upper and lower edges oi the free ends of said rod sections forming the ends of said curtain rod to said hooks of said brackets and bowed outwardly away from the window casing to` which the brackets are fastened in use comprising alined apertures in the upper and lower edges of said ends adapted tc pivotally t over `said hooks, whereby said rod will be held against twisting and sagging from the horizontal position with its flat portions vertically disposed regardless of the spacing of the brackets within the extension limits of the curtain rod.

4. In a curtain rod having a pair of brackets adapted to be attached to a window casing, a pair of relatively nat telescoping sheet metal rod sections having portions identically curved flatwise into circular arcs forminga curtain rod bowed horizontally away from a line between said brackets and means for 'pivotally connecting the f'ree ends of said rod sections forming the ends oi said curtain rod on vertical axes to said brackets in such a manner that said rod will be bowed outwardly away from the window casing to which the brackets are fastened in use and held against twisting and sagging from the horizontal posi- `tion with its at portions vertically disposed regardless ot the spacing oi the brackets within the extension limits of the curtain rod.
